ROTARY CHURN.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed June 30, 1908. Serial No. 441,096.

To all whom it may concern:

Be it known that I, STANSBURY JACOB SMITH, a citizen of the United States, residing at Hot Springs, in the county of Garland and State of Arkansas, have invented a new and useful Rotary Churn, of which the following is a specification.

This invention relates to churns, and more particularly to the type known as rotary churns.

One object of the present invention is the construction of a support for the churn whereby the latter may be readily operated from a standing or sitting position.

Another object is to so construct the support that it can be readily adjusted to the various sizes of tubs. And still another object is to provide a novel method for detaching the actuating mechanism in order to remove the churn from the support.

l Vith these and other objects in view as will more fully hereinafter appear the present invention consists in certain novel details of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that various changes in the form proportion, size and minor details of the device may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming a part of this specification. Figure 1 is a perspective view of the device showing a churn attached thereto. Fig. 2 is a detailed perspective of the adjusting bracket. Fig. 3 is a side elevation of the driving wheel and a sectional View of the support for the same disclosing the arrangement for sliding the driving wheel to disengage the chain with the pinion.

Similar numerals of reference are employed to designate corresponding parts throughout.

In the construction illustrated in Fig. 1 a churn is shown supported in an inclined position by the frame, and the actuating mechanism supported so as to form the side of a triangle with the plane of the churn, this construction permits the latter to be operated with less fatigue than if the actuating mechanism lie in a vertical plane since it is obvious if the latter construction were employed the bending motion which the operator would have to undergo in the course of the churning process would prove exceedingly tiresome. The base 1, of the support is preferably formed of wood, metal, or other suitable material and is intermediately provided on its upper face with a standard 2, which extends perpendicular to the base 1, as shown. The standard is rigidly supported by means of a strut 3, of substantially the same width as the standard having one end secured adjacent the upper end of the latter and its opposite end secured adjacent one end of the base 1. adjacent the opposite end of the base 1 are the chocks l, preferably three in number, which form a support for the lower end of the churn 5. The outer and middle chock are provided with flat upper faces forming a level platform to support the churn in an upright position, while the upper face of the inner chock is provided with a semi-circular depression conforming to the configuration. of the lower end of the churn body 5. Secured to the intermediate portion of the standard 2, and opposite the strut 3, are guide bars 6, extending downwardly and outwardly at substantially an acute angle to said standard and forming a support for a bracket '7, preferably formed of wood, metal, or other suitable material, and provided adjacent its opposed sides with openings adapted to fit over the guide bars 6.

The upper end of the bracket is provided with a concave surface similar to and lying in an incline plane with the inner chock 4, so that when the lower end of the churn body is tilted and brought to bear upon the concave surface of the inner chock 4, its upper or opposite end will be engaged by the concave surface of the bracket 7 thus it will be seen that the working position of the churn will be inclined-it being designed to have such incline extend beyond the vertical center of the churn so that the latter will be held in place by its own weight as shown in Fig. 1. It will also be observed that the bracket 7, can be moved longitudinally on the guides G, and the distance between the inner chock increased or diminished according to the size of churn body used.

The actuating mechanism in the present instance consists of a sprocket wheel 8, r0- tatably mounted on a shaft 9, secured to an oblong block 10; the latter is preferably formed of wood or other suitable material and is pivotally secured to the upper face of the strut 3, by means of the bolt 11, en-

On the upper face and tering an opening adjacent one end of the block disposed on the upper face of the strut 3, and directly beneath the block 10 is a stationary prop 12, the function of this member being to form a support for the block 10, and limit its pivotal movement in one direction a dog 13 is shown in Fig. 3 as being pivotally secured to the upper face of the strut and on the opposite side of the block 10, its function being to engage the upper side of the block when the lower side of the latter is resting on the prop 12 it is evident with this construction when the dog 13 is brought to bear on the block 10 that movement of the latter on its pivot 11 will be prevented. The sprocket wheel 8 is in direct alinement with a pinion 14L, keyed to and adjacent the outer end of the dasher shaft 15 the inner end of which is in the churn body and carries the usual type of rotary dasher, the intermediate portion of the shaft is journaled in a central opening formedin the head 16, of the churn and the upper portion beneath the pinion lat, enters a vertical socket 17 formed in the upper end of the standard 2, a suitable sprocket chain 18 connects the pinion with the hand wheel 8, and the latter is turned by means of a handle 19, so that when the parts occupy the position shown in Fig. 1, by turning the hand wheel 8 motion will be communicated to the dasher shaft 15.

hen desired to disengage the churn, and allow it to resume a vertical position the same is accomplished by moving the dog 13 to the right or left which will permit the block 10 to be moved upward on its pivot 11, so that the chain can be detached from the pinion let.

What is claimed is 1. A churn support embodying a base, a vertical standard secured thereto, a chock on said base provided with a concave face, a bracket carried by said standard having concave face lying in an inclined plane with the concave face of said chock.

2. A churn support embodying a base, a vertical standard secured thereto, a plurality of chocks on said base, one of said chocks being provided with a concave upper face, an adjustable bracket on said standard having a concave face lying in an inclined plane with the concave face of said chock.

A churn support embodying a base, a vertical standard secured thereto, a plurality of chocks on said base, one of said chocks being provided with a concave upper face a strut connecting said standard with said base a pair of guides secured to the opposed face of said standard, a bracket slidingly fitted on said guides said bracket provided with a concave face lying in an inclined plane with the concave face of said chock.

4E. The combination with a churn and dasher shaft, of a support having a vertical standard, a strut having one end secured to one face of said standard and its opposite end to said support, a bracket on the opposed face of said standard adapted to support said churn in an inclined position, an actuating mechanism carried by said strut having connection with said dasher shaft, and adapted to rotatethe latter in a plane with the axis of said churn.

5. The combination with a churn and dasher shaft of a base plate having chocks adjacent one end forming a support for one end of said churn, a standard secured to said base plate having a bracket on one face thereof forming a support for the opposed end of said churn when the latter is in an inclined position, a strut connecting said standard with said base, an actuating mechanism carried by said strut having connection with said dasher shaft and adapted to rotate the latter in a plane with the axis of said churn.

6. The combination with a churn and dasher shaft, of a support provided with a chock having a concave face, and a bracket provided with a similar face lying in an inclined plane with said chock and serving to support said churn and dasher shaft in an inclined position, a pinion adjacent one end of said dasher shaft, a hand wheel adjustably mounted on said support and a flexible connection between said hand wheel and said pinion.

7. The combination with a churn and dasher shaft, of a base having a chock provided with a concave face forming a support for the lower end of said churn a standard on said base having on one face a bracket provided with a concave face forming a support for the upper end of said churn when the latter is inclined to said base. a brace for said standard, a block slidingly mounted thereon a hand wheel on said block, a pinion at one end of said dasher shaft, and a flexible connection between said pinion and hand wheel.

In testimony that I claim the foregoing as my own, I'have hereto afiixed my signature in the presence of two witnesses.

STANSBURY JACOB SMITH.
